This large (and very heavy at nearly 5 pounds!) is in a transparent amber brown sometimes referred to as 'root beer'. It has a bulbous bottom with a tall narrow neck - a traditional Chinese form.
It is in excellent condition. It displays a few internal bubbles which is typical of these pieces. It is not signed so dating is mainly by experience with other similar pieces and we approximate the age of this art glass piece to be 19th century. Although the book below assigns an earlier date to the similar pieces, we are without benefit of expert verification of the age so are taking a more conservative approximation of the age.
It measures 12" tall and is about 6" in diameter at the widest, bulbous area. It is 2 3/4" in diameter at the top. As you can see the walls of this vase are very thick and measure approx. 5/8" at the top and 1/2" further down.
Based on information found in the book, A Chorus of Colors - Chinese Glass from Three American Collections published by the Asian Museum of San Francisco, this piece exhibits many similarities to two pieces illustrated in the book that are identified as being 18th century pieces.
One vase on page 68 describes the vessel thusly: "Massive and beautifully shaped, this vessel has a slightly recessed base...The vessel is transparent with a few scattered bubbles. The edge of the base and the mouth are slightly beveled, the mouth on both the inside and outside lip."
On page 24, the shape of the lip and the base are very much like the vase listed here.
